These may look like typical landscape photographs, but hidden inside each one is a sniper with a gun pointed at the camera lens.

The German Army provided photographer Simon Menner with two snipers for his Project Camouflage series, which puts the viewer in the crosshairs of an apparently invisible military professional. Menner has provided clues to the location of the sniper in each image. For example, in the top image:

Sniper above the brownish rotten wood. Slightly to the right. Spotter behind him to the left.

Menner also recently published a rather fascinating looking book, Top Secret: Images from the Stasi Archives, which collects photos he unearthed on the East German secret police and his research into their activities. Thanks to Menner for letting us feature these photos here.
